7 fication.

This invention relates to folding umbrellas, and more particularly to afolding um brella of that class in which the ribs of the umbrella arejointed intermediate their ends so as to be foldable upwardly andinwardly intc parallelism with the umbrella stick or sta One of the mainobjects of the invention '7 is to provide an umbrella of the characterstated which, when folded, will occupy a minimum of space and may beeasily carried in a suit case, pocket, or the like. A further object isto provide an umbrellain which the ribs are moved into and out ofoperative position by the action of radially disposed operating rodsslidably and pivotally connected to the umbrella staff. A further object is to' provide an umbrella having a telescoping staif of simpleconstruction which, when in operative position, will rigidly support theumbrella head. Further objects will appear from the detail description.

In the drawings: Figure 1 is a side view of an umbrella embodyingmyinvention in raised position,

the head of the umbrella being shown as sec- ,tioned transversely.

'Fig. 2 is a view showing the ribs of the umbrella in lowered position.

, Fig. 3 is a view showing the ribs as folded upward and inwardpreparatory to'moving the head of the umbrella into completely foldedposition.

, Fig. 4 is a central vertical section through the umbrella staff.

Fig. 5 is a fragmentary section through the staff.

Fig. 6 is a fragmentary detail view of the jointof one of the ribs andthe connection beiirween the same andone of the toggle arms.

7 is a detailed fragmentary sectional The umbrella stafi' is composed ofthree telescoping sections numbers 1,2, and 3. Sect on 2 is slidable inthe top section 1,

and a lower section 3 is slidable' in the inleaf spring projects througha slot 6 through the wall of the stafi' section and is 'provided, at itsinner end, with an approximately square lug 7. This lug is adapted tofit into a corresponding recess through the wall of the intermediatesection 2, thus looking section 2 against longitudinal movement when inextended'position. The top section 1 is provided, in its inner face,with a longitudinally extending groove 8 which terminates a shortdistance from the lower end of this section. This groove is positioneddiametrically opposite to the spring catch 5 and is adapted to receive astub 9 projecting from section 2. The stub and groove cooperate toprevent a complete withdrawal of the section 2 from section 1, and alsoact to insure that the opening through section 2 will at all times bebrought into register with the lug 7 of spring 5. When it is desired tomove section 2 into inoperative position, spring 5 is moved outward soas to disengage the lug 7 from the co5perating aperture of this section.For this purpose the free end of the spring is turned upward at rightangles to provide a finger grip 10. Sections 2 and 3 of the stafl' aresecured together in the same manner as sections 1 and 2. By thisconstruction the staff may be quickly and easily'extended, or may betelescoped so as In the upper end of the top staff section 1 is secureda cylindrical plug 11. A disk 12 is secured about this plug andrests onthe upper end of section'l. This disk is pro- ,vided with a plurality ofradially disposed to occupy very little space.

the cars 13 of the disk 12, in the usual manner. Each of these ribs isformed of two sections 15,and- 16.. These two sections eare of equal;length "and are pivotally secured at f their adjacent ends in a U linkmember 17. This link member has its base bar or wall positioned beneaththe sections 15 and 16 of the rib. By this construction the downward Imovement of the outer rib section 16 about its pivotal axis ispositively limited, while this-rib section is" free to fold upward andinward about its pivotal .axishintowparal lelisin with the upper ribsection 15.

This produces a very compact bundle which occupies very-little space. Bylifting the springs 5 into inoperative position and forcing the sectionsofthe staff into-each other,

the total length of-the umbrella when folded will be butslightly-greaterthanthe-length of the top section 1 ofthestafi'i- Whenthus foldedthe umbrella may be easily inserted a into a suit case on thelike; ormay be even carried in the pocket, i-f-desired.

To permit proper folding of theau'mbrella head, the inner sections 15 ofthe -rib, the arms 19, and the rods 24,-are all out. ofveraticalalinement For this purpose the outer end of arms 19 androds 24 are bentor ofll set so as to-permit proper operation of -the same, asin Figs. .2and 3 of the drawings.

In order to secure the umbrella inopen position it isnecessary o-providemeans for .secur-ing-the-sleeve 22 in adjustment omthe -umbrella;stafi.-For this-purpose Iprovide a: pair of spaced: lugs 27 which projectoutwardly from the sleeve. sThese lugs ipivotally support 'a'thu-mblatch 28- theeupper-end of which isturned inward at rightfangles toprovide a-lug orwdetent 29-operative through a suitable aperture throughsleeve 22,-; -W-hen the sleeve *is in its 'outermostpositionthe-de v-.tent:- 29 is brought into register with-a; re- 4 01 the arms 19.outward radially thus extending eess formed in thewall of theupper-staff section 1,! and is forced intothersame'by a coil spring 30confinedbetweenthe-lowerenlarged end 31 of the latchv 28 and the sleeve22.
